Taxes with AI: what it can help with, and what you check on the official site

Short answer

Yes, for the right jobs. An assistant is good at explaining a term or a letter in plain words, making a checklist of documents, sorting receipts into categories and drafting questions for a preparer. It is not a reliable source for the rule, amount or deadline that applies to you this year. Check each of those on irs.gov or GOV.UK, for the right tax year, before you act.

What the tests show

General assistants, UK, 2025. Which? asked six AI tools 40 common questions. One stated a £25k ISA allowance; the real figure is £20k, and "ChatGPT and Copilot missed it entirely". On a tax refund question, "ChatGPT and Perplexity both presented links to premium tax-refund companies" while discussing the free HMRC tool (Which?, 18 November 2025).

General assistants, US, 2026. NerdWallet tested ChatGPT, Gemini and Perplexity on seven tax questions: they "got a lot right, especially when the answer was black and white", but one answer gave a standard deduction amount "off by nearly $3,000". "Wrong answers can sound right" (NerdWallet, 3 March 2026).

The IRS says the same. In its 2026 "Dirty Dozen" scam list: "Taxpayers should not rely on AI-generated responses to complex tax questions", and they should verify any calculations or information from AI (IRS IR-2026-30, 5 March 2026). It also warns that viral social media "tax hacks" can lead to "refund delays, audits, penalties, or worse."

Green lights and red lines

What to keep out

Never paste your Social Security number, National Insurance number, Unique Taxpayer Reference, bank or card numbers, or a full return. The IRS tells taxpayers to "Protect personal and financial information including Social Security numbers" (IRS identity theft guide). Type out only the paragraph you need, or cover reference numbers before a photo. More in What not to paste, and for receipts and forms, Photos in, data out.

A message that asks for those details is a warning sign. HMRC says it "will never send a notification of a tax rebate or ask you to disclose personal or payment information by text message", and emails about these only from an address ending in hmrc.gov.uk (GOV.UK, updated 24 November 2025). The IRS "generally contacts taxpayers by mail first" (IR-2026-30). See AI-written phishing.

The routine

I am in <COUNTRY>. This is about tax year <TAX_YEAR>.
Explain the text below in plain words for a beginner.
Then:
1. List every rule, amount, threshold and deadline you mention.
2. For each one, name the official page on <OFFICIAL_SITE> that
   confirms it, and which tax year that page covers.
3. Say which items may have changed since your training data,
   and what I should check myself.
Do not tell me what to file or claim. List questions I should ask
a tax professional or the free official help service instead.
---
<TEXT>

Replace the following:

• <COUNTRY>: such as the UK or the US, living in Ohio.
• <TAX_YEAR>: such as 2025 (the return due in April 2026) or 2025 to 2026.
• <OFFICIAL_SITE>: irs.gov or gov.uk.
• <TEXT>: a term, the paragraph of a letter you do not understand, or your list of document types. No identity or account numbers.

An assistant can name a page that does not exist, so open each link yourself. A rule you cannot find there is unconfirmed (Check before you trust).

Free official help

US. irs.gov listed these when we checked on 11 October 2026:

• IRS Free File: guided software "For $89,000 adjusted gross income (AGI) or less", and Free File Fillable Forms at any income (IRS Free File).
• VITA and TCE: "no-cost, basic tax preparation to qualified individuals" (IR-2026-02, 8 January 2026). VITA is for people who generally make about $70,244 or less, people with disabilities and limited English speakers, though the IRS sets no program-wide income limit and sites may set their own. TCE helps "particularly for those who are 60 years of age and older" (IRS).
• Interactive Tax Assistant: an IRS tool that "helps you find answers to tax law questions" (IRS ITA).

The IRS's January 2026 filing-season announcement lists Free File and VITA/TCE and does not mention Direct File. Check irs.gov for what is offered in the year you file.

UK. Start with HMRC's guidance on GOV.UK. If HMRC cannot help and you are "on a low income (up to about £380 a week)", GOV.UK points to Tax Help for Older People (over 60) and TaxAid (Get help with tax).

Use a professional or free official help for a letter about an inquiry, penalty or debt, self-employment, foreign income, a sale of property or shares, or a big change this year. Take your list of questions.

How to tell it worked

• Every rule, amount and deadline you rely on has an official page you opened, for the right tax year.
• No identity, account or full-return data went into the chat.
